Resonator-Based Filters with Frequency Modes Close to Metamaterial Cells

Abstract

Background. Many of the properties of metamaterials are similar to those found in the filter on mutually detuned frequency and unrelated resonators. The bridge filters are used as a low-frequency prototypes of such microwave filters. It is important to establish an analogy between metamaterials and filters on mutually detuned frequency and unrelated resonators for further development and design of new types of metamaterials.

Objective. A central objective is a model development of metamaterials based on band-exclusive microwave filters on mutually detuned resonators, and the low-frequency-based prototypes.

Methods. Characteristic equivalence test of metamaterials to microwave filters on mutually detuned resonators, their specific dependencies reveal (the modes in parallel channels, the locations of the attenuation poles above or below the bandwidth), manifested regardless of the types of resonators, the study of the possibility of the bridge filter prototypes using for metamaterials simulation.

Results. The analogy between metamaterials and microwave filters on mutually detuned resonator is specified, the possibility of bridge bandpass filter use as low-frequency prototypes is shown.

Conclusions. Microwave filters on mutually detuned resonators, and bridge band-pass filters as low-frequency prototypes, design techniques of which are well established, can be used for metamaterial modeling.
